In addition, TS may deploy vcpu vs. Logical Cores, but only if it is deployed by itself on a host, or co-resident only with non-Cisco-Collaboration apps that also allow deploying vcpu vs. Logical Cores. E.g the 20-vcpu VM deployed against Logical Cores on a host that only contains TS VM and non-UC apps would only require 10 physical CPU cores on that physical server.

Recall that none of the other Cisco Collaboration apps support CPU oversubscription and are requried to deploy vcpu vs. Physical Cores even when hyper-threading is enabled in the physical CPU.
